To get back up and running you are going to have to reset the unit. This is from the handbook:

Note: Take care - factory reset clears allWaypoint and Route databases.
➤ To perform a factory reset:
1. Power off the unit.
2. Press and hold CLEARwhilst powering up until <Erase backup procedure>
is displayed.
3. Either press CLEAR to abort Factory Reset and resume normal
Power-Up or press ENTER to continue Factory Reset.
4. Press ENTER again; the unit restarts as for a first time PowerUpwith
all values reset to their original factory settings

When you hit port and have an internet connection, make sure you are running the latest software version, currently listed online as version 1.09. You can download it here:

Probably a bad printed circuit board, just had to send mine in to have it repaired. When I hit the power button, I did hear a beep, but then nothing displayed. Mine was still under warrenty, so don't know the repair cost if yours is not.

The C Series units have a specific cable that connects directly to the DSM. The GPS antenna has multiple wires that will need to be connected to the "SeaTalk" port on the C80. The SeaTalk cable comes with the display. The GPS connects as indicated in the following link :
